I used to use a handy craft addon. All it did was if you Alt-Clicked on items in your craft panels it would print out the mats in your current chat window. So if someone said "Link mats for Belt of Deep Shadow" you just alt clicked it in your leather working panel and the mats got listed. I think the addon got discontinued and I've forgot the name of the addon so I can't find it anywhere.
Can anyone remember the addon and if it is still active.
